The stress versus strain graph is shown for two wires. If $$Y_1$$ and $$Y_2$$ are Young modulus of wire A and B respectively, then the correct option is:

1. $$Y_1>Y_2$$
2. $$Y_2>Y_1$$
3. $$Y_1=Y_2$$
4. cannot say

The stress-strain curves are drawn for two different materials $$X$$ and $$Y.$$ It is observed that the ultimate strength point and the fracture point are close to each other for material $$X$$ but are far apart for material $$Y.$$ We can say that the materials $$X$$ and $$Y$$ are likely to be (respectively):

 1 ductile and brittle 2 brittle and ductile 3 brittle and plastic 4 plastic and ductile
